What affects the strength of intermolecular forces?
Intermolecular forces affect many properties of compounds, such as vapor pressure and boiling point.
The structure of a compound can influence the formation and strength of intermolecular forces.
The branched alkane has fewer opportunities to form London dispersion forces compared to its straight-chain counterpart..
How does the strength of intermolecular forces affect viscosity?
Viscosity increases as intermolecular interactions or molecular size increases. … Viscosity decreases rapidly with increasing temperatures because the kinetic energy of the molecules increases, and higher kinetic energy enables the molecules to overcome the attractive forces that prevent the liquid from flowing.
What affects the strength of dipole dipole forces?
Within a series of compounds of similar molar mass, the strength of the intermolecular interactions increases as the dipole moment of the molecules increases.
What is the strongest intermolecular force?
hydrogen bondingThe strongest intermolecular force is hydrogen bonding, which is a particular subset of dipole-dipole interactions that occur when a hydrogen is in close proximity (bound to) a highly electronegative element (namely oxygen, nitrogen, or fluorine).
Which compound has the strongest intermolecular forces?
hydrogen bondsDispersion forces are the weakest intermolecular force (one hundredth-one thousandth the strength of a covalent bond), hydrogen bonds are the strongest intermolecular force (about one-tenth the strength of a covalent bond).
